The currently ongoing observation run (called O4b) of the gravitational wave observatories LIGO and VIRGO was meant to continue until June 9, 2025. This schedule has just been updated: an additional break for repairs will take place from 1 April 2025 to 4 June 2025. Observations will then resume and the O4b data taking period has been extended to until 7 October 2025.
After some major upgrades, observations will then restart with the run O5 in 2027.
Fingers crossed to detect another binary neutron star merger until October!
